My 5 year old Fujitsu Livebook had more and more problems to connect to WLANs. I then bought the Intel 6205 network adapter and have since better signal strength and no problems of any kind more. However, this map of Windows 7 is not recognized after installation. Rather, you must download from Intel a tool that analyzes the Intel components are in the laptop, and then the drivers for it installed / updatet. Expenses for: About an hour and well over 100 MB download volume. If everything runs smoothly.
